The policy making people are all appointed by the President. When Sarah appoints me to a job I can guarantee her that I'll destroy the coherency of that agency within 6 months ~ then I can return to going blind and thinking about political theory.
BTW, that's no idle boast.
You would have to R&R every person in the party infrastructure NATIONALLY vs putting a new structure together your way from day one. $$$ and time we have little of. You still need to deal with all the side deals/dealers, ‘culture’ etc of what you inherit.
My point is why? Why waste it all and still have the legacy of failure for your efforts? It makes zero sense. If this was a company, there would never be a new management team as no one would buy it to begin with.
MAYBE to sell off the assets, but the GOP has none.
